The Global Temperature-Salinity Profile Program (GTSPP) is a cooperative international project that seeks to develop and maintain a global ocean Temperature-Salinity resource with up-to-date and high quality data.

Purpose
Making global measurements of ocean temperature and salinity (T-S) quickly and easily accessible to users is the primary goal of the GTSPP. Both real time data transmitted over the Global Telecommunications System (GTS), and delayed-mode data received by the NODC are acquired and incorporated into a continuously managed database. The Global Telecommunications System (GTS is a global network for the transmission of meteorological data from Weather stations Satellites and numerical
International contributors
Several countries contribute to the GTSPP. They are:
Canada's Marine Environmental Data Service (MEDS) leads the project, and has the operational responsibility to gather and process the real-time data.

Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. For a topic outline on this subject see List of basic Japan topics. Russia (Россия Rossiya) or the Russian Federation ( Rossiyskaya Federatsiya) is a transcontinental Country extending The United States of America —commonly referred to as the MEDS accumulates real-time data from several sources via the GTS. They check the data for several types of errors, and remove duplicate copies of the same observation before passing the data on to NODC. The quality control procedures used in GTSPP were developed by MEDS, who also coordinated the publication of those procedures through the Intergovernmental Oceanographic Commission (IOC). In Engineering and Manufacturing, quality control and quality engineering are involved in developing systems to ensure products or services The Intergovernmental Oceanographic Commission was established by resolution 2
The U. S. National Oceanographic Data Center (NODC) performs four functions for the GTSPP:
- Maintains the global database of temperature and salinity data and provides online access to the data. The National Oceanographic Data Center (NODC manages the acquisition ingest processing quality control and long-term preservation of oceanographic Data.
- Adds realtime data supplied by MEDS to the database.
- Processes delayed mode copies of data by performing the same data quality tests as MEDS, then adds data to the database.
- Prepares monthly data sets and transfers them by network to participants in the U. S. , Australia and France, as well as to requestors.
In addition to MEDS and NODC, three science centers participate in the project by independently evaluating the delayed-mode data sets for the Indian, Pacific, and Atlantic Oceans. The Indian Ocean is the third largest of the world's Oceanic divisions covering about 20% of the water on the Earth 's surface The Pacific Ocean is the largest of the Earth 's Oceanic divisions Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), the Scripps Institution of Oceanography (SIO), and NOAA's Atlantic Oceanographic & Meteorological Laboratory (AOML) perform this function as Data Assembly Centers for the World Ocean Circulation Program, which the GTSPP supports. The Commonwealth Scientific and Industrial Research Organisation ( CSIRO) is the national government body for scientific research in Australia. Scripps Institution of Oceanography (sometimes referred to as SIO, Scripps Oceanography or just Scripps) in La Jolla California, is one of the The National Oceanic and Atmospheric Administration ( NOAA) is a scientific agency within the United States Department of Commerce focused on the conditions of the
Infrastructure
The GTSPP consists of four major components:
- Global Telecommunication System (GTS): Carries real-time data from ships and buoys in support of the IOC/WMO Integered Global Ocean Services System (IGOSS).
- IODE Data Centers: Contribute data, monitor the project, and distribute products. These are national oceanographic data centers which participate in the International Oceanographic Data & Information Exchange (IODE) System of the International Oceanographic Commission.
- Continuously Managed Database (CMD): Maintains the up-to-date global temperature-salinity data, replaces near real-time records with higher quality delayed-mode records as they are received, and creates and distributes copies of the data on CD-ROM and other media. CD-ROM (an initialism of "Compact Disc Read-Only Memory " is a pre-pressed Compact Disc that contains data accessible to but not writable
- WOCE Data Assembly Centers: Perform scientific quality control through data analysis, and issues products and predictions based on the global temperature-salinity data set.
